Early SSDs had a reputation for failing after fewer writes than HDDs. If the swap was used often, then the SSD may fail sooner. This might be why you heard it could be bad to use an SSD for swap. Modern SSDs don't have this issue, and they should not fail any faster than a comparable HDD. Placing swap on an SSD will result in better performance than placing ...

Still today Flash RAM cells built in SSDs have a limited lifespan. Every write (not read) cycle or better every erasure wears a memory cell and at some time it will stop working. The amount of erase cycles a cell can survive is highly variable, and flash from modern SSDs will do much better than some years ago. In addition the intelligent firmware will take ...

HDD technology uses a magnetic process for data manipulation and storage. This process is noninvasive, meaning you can pretty much manipulate data on a disk drive infinitely. That is until the mechanics start to fail. In contrast SSD technology does not run the risk of mechanical failure. But what is a concern is how it stores it's data. For data storage ...

Depending on how much RAM your system has, you can get away with using very little swap, and even then, your computer will only use swap when it runs out of space in RAM. Obviously, writing to the SSD will shorten its lifespan, but as long as you avoid using utilities that make many small writes (like defragmentation) you should be fine. Hibernate works by ...

Concerns about swap on SSDs are unfounded. They can handle a good 10,000 writes, so to wear out a 500 GB SSD you would have to write 100 MB / second to it every second for for 578 days. There is no way you are going to manage to keep it constantly swapping that much for that long, and certainly writing 1-2 gb for hibernation once or twice a day is not ...

As long as there is free memory available, the system will never use swap. In fact, swapping should be avoided in a system as possible... On the other hand, in your case, it seems that you don't have a swap partition. Otherwise you should see something like this: $ swapon -s Filename Type Size Used Priority /dev/sdb1 ...

Roughly explained, RAM is used by two things: Loaded programs Harddisk cache to speed-up read- and write-access If a program is started but doesn't use some parts of its allocated RAM, it will be swapped to disk to make space for harddisk cache to improve harddisk performance. The aggressiveness of swapping out programs is called swappiness. You can ...
